After looking into this more carefully, I learned that org-add-link-type is deprecated. In case anyone else runs into this, the solution is to edit org-mu4e.el, replacing the lines
(org-add-link-type "mu4e" 'org-mu4e-open) (add-hook 'org-store-link-functions 'org-mu4e-store-link) with the single line (org-link-set-parameters "mu4e" :follow #'org-mu4e-open :store #'org-mu4e-store-link) I'll report this to the mu developer in case he isn't already aware of the upcoming change in org mode. I wonder if org-mu4e.el wouldn't be better maintained as a part of org (like org-gnus.el and org-mew.el) rather than as a part of mu4e.

I really depend on this functionality.
